It's because he's Justin Bieber! Everything he does is like so unique, funny and cool!!!! "LOL i'm gonna wear overalls to meet the prime minister because it's sooooo funny lololololollllll!!!!!!!!!! **** you justin bieber...

I'm more pissed at the fact he wore that to get his ******* diamond jubilee medal. He doesn't even remotely deserve one, and on top of that, it's supposed to be a formal, honourary medal from the queen or some **** , and he comes in dressed like ******* Doug Mackenzie.
